Second symbol indicates that it&rsquo;s a <a href="http://3.bp.blogspot.com/-WOK_YZTAVw4/T8hailCDoMI/AAAAAAAAAK0/AzHthJ8U9zI/s1600/panel+meter+1.jpg" rel="nofollow" >moving coil</a> type.<br/>
The 2.5 is its <a href="http://en.wikipedia.org/wiki/Class_of_accuracy_in_electrical_measurements" rel="nofollow" >wikipedia:class</a> value.<br/>
The third symbol is probably more a &ldquo;pay attention to this when reading values&rdquo; thing than a &ldquo;danger will robinson&rdquo; thing.</p>
<p>Edit: Was hoping to find a nice reference overview other than my crappy old schoolbook, and a random manufacturer (ESP Technologies) delivers: <a href="http://www.esptechno.com/NOVA/PANEL%20METER.pdf" rel="nofollow" >NOVA PANEL METER(ANALOGUE) - Page 2: Symbols for Marking Instruments and Accessories</a>.<br/>
Which in turn tells me that the third symbol does have a defined meaning: <em>Warning: see application instructions</em>.</p>kfitch42 on TOL-11866 - Analog Panel Meter - 0 to 20mA (Ding and Dent)kfitch42urn:uuid:41ca8206-36d8-7fda-af33-4f9ba6dff7012013-05-31T13:01:29-06:00<p>Looks like we are being warned about &hellip; something to do with 2.5 &hellip; on the lower right.

<p>It could of been worse I suppose. They could of shown up looking like this: <img src="http://www.centaur.org/mameter.jpg" rel="nofollow" alt="" /></p>

<p>Still, useful meters!</p>Kamiquasi on TOL-11866 - Analog Panel Meter - 0 to 20mA (Ding and Dent)Kamiquasiurn:uuid:20007754-77fd-7243-6d7b-9fa2de2c97be2013-05-31T10:02:40-06:00<p>See the screws? That&rsquo;s usually pretty much it. The panel <em>may</em> also be glued down, often making it impossible to remove it without bending it or having lots of patience + glue dissolve.</p>jbookout on TOL-11866 - Analog Panel Meter - 0 to 20mA (Ding and Dent)jbookouturn:uuid:cd8be1df-ee77-592d-d6b7-2e9a3a70b39e2013-05-31T09:42:59-06:00<p>Can these be easily opened to replace the panel?</p>RobertC. on TOL-11866 - Analog Panel Meter - 0 to 20mA (Ding and Dent)RobertC.urn:uuid:fbe3feae-b365-4bae-da35-37cae54185f82013-05-30T14:23:14-06:00<p>haha, right?</p>Mitch.Tolson on TOL-11866 - Analog Panel Meter - 0 to 20mA (Ding and Dent)Mitch.Tolsonurn:uuid:17628b6f-57d8-6432-c497-69b8914777682013-05-30T12:13:35-06:00<p>Look good boss?
